    Tasking the most advanced satellites


WorldView-2 is the first high-resolution 8-band multispectral commercial satellite. It was launched in October 2009. Operating at an altitude of 770 kilometers, WorldView-2 provides 46 cm panchromatic resolution and 1.85 meter multispectral resolution.

WorldView-2 has an average revisit time of 1.1 days and is capable of collecting up to 1 million square kilometers of 8-band imagery per day.

The WorldView-2 system, offers incredible accuracy, agility, capacity and spectral diversity, substantially expanding its imagery product offerings to both commercial and government customers.
